Unitilite will not play mp3 files from vinyl records

My Unitilite has recently stopped playing mp3 music files from vinyl records but plays mp3 files from CD’s. It has quite happily played all the files for many years from my Synology NAS but stopped playing those mp3 files based on vinyl records about 10 days ago.
Does anyone have any solutions

Have you recently upgraded the firmware on the Unitilite?

Unless you especially want to know why they now don’t play, your easiest solution might be to (off line) transcode them to flac.

There are other instances of files now longer working, which is suspected to be related to firmware 4.9 hence the question.

I got the same problem even with specific FLAC files (bit rate higher than 3000 Kbps and sample rate at 96 KHz). I was not able to identify the root cause. After a second automatic retry, the files affected by the previous problem can be played through the USB interface. Strange, really strange!

Fair enough. Potentially an update to the Synology too. Evidently something has changed… :person_shrugging:

Thanks.I will check if it updated when the internet radio fix was installed last month.

Thanks Andy for your suggestion. The Synology has been updated but after this problem occured.

If you ripped these yourself, worth just checking if they are set at “Joint Stereo”. Plenty of articles on this Forum.

MP3 files with Stereo Mode = “joint stereo or stereo” might be affected with firmware 4.9. It depends neither on the network nor on the NAS/software.

I had this problem even with WAV. I’d record a record with my TEAC ADC and if they were 24/192 then the NDX would play maybe 1 in 5 and refuse to play the others. This is on the older 4.7 firmware. Lowering to 29/96 resolved the issue and I have no idea why. Nor do I have the time or interest to dig deeper.

I thought there might be a correlation with file size but no. And as all tracks were recorded in the same session they got output with the same configuration.

The other solution was to repack as FLAC using dbpoweramp. The same WAVs that failed as WAV, suddenly worked. Even though the NAS transcodes back to WAV again.

There are times where life is too short once you have a solution to bother with root cause analysis.

Hi. Thanks for all the helpful advice. I think the problem lies with the 4.9 firmware update. The solution which seems to work, as you suggested, is to convert the offending files to FLAC, and in that format they now play.

Well I have the problem on Firmware 4.7. Though it might be a similar but different problem with the same solution.
